The other day I saw the first two pics on a “seen on the street” blog called the “Satorialist.” The (I’m guessing unintentional) juxtaposition of these two looks made each one stand out more.
Both people are accessorized, one is after a traditional look of feminine beauty, while the other is striving more towards self-expression and mixing cultures.
The other three pics are from around the web representing different takes feminine beauty and accessorizing from only using body paint, to a small bikini and fake boobs, to a formal full length evening gown.
I’m not trying to leave out men entirely, it’s just easier to focus more on the spectrum of accessorizing used by women. It’s in general a richer and broader palette.
Other animals differentiate themselves but not by accessorizing and without regard to evolutionary pressures. Humans do it for fun and often times without being concerned about attracting a mating partner, although at the extreme end some people are attractive because they’re different.
Any “look” is a message, even the choice to not have a “look.” A person’s look is a signal to other people. Once the look transgresses the traditional the signal can be and is interpreted unpredictably.
